Motion sensor with identification
Halbich, Václav ; Matěj, Zdeněk (referee) ; Fedra, Zbyněk (advisor)
The solution of the motion detection system with the parallel radio identification on the same channel/carrier. The work is based on the RF sensor from ALPS Electric (product still in development phase), which works as an RF motion sensor and a digital transceiver as well. System can differenitiate general moving object from an object with active key. First part of this work describes the sensor module and the internal Nordic nRF24LE1 transciever (physical layer). Design of packet based communication protocol which does not influence motion sensing (communication layer) is discussed. Next part consist of FW design of application and identification protocol for sensor and key (application layer) and reference HW design of the active key. There are series of tests in every section.

Wireless interface to control digitally controlled components
Halbich, Václav ; Kubíček, Michal (referee) ; Ševčík, Břetislav (advisor)
e bachelor thesis deals with problem of wireless communication between digitally controlled components. Universal Bluetooth modules are used to construct the multifunction wireless interface. The first part is focused on description of SPI, I2C, Up & Down data bus. Subsequently, the selected Bluetooth modules are described. Finally, the application of wireless interface to control of digital potentiometers is discussed.
